Prior Authorization

Up to $ per case, excluding expenses, may be expended on other services without
prior authorization, subject to subsequent review. Fees expended on services with prior authorization do not count towards the "$ without prior authorization" limit. Once the "$ without prior authorization" limit is reached, prior authorization is required for all services, unless it is waived by the presiding judge upon a finding that, in the interest of justice, the timely procurement of necessary services could not await prior authorization.

Limitation on Fees and Expenses

With respect to federal capital prosecutions and federal capital
habeas corpus proceedings, the fees and expenses for investigative,
expert, and other services are limited to $ in any case unless: (1)
payment in excess of that amount is certified by the court as necessary
to provide fair compensation for services of an unusual character or
duration; and (2) the amount of the excess payment is approved by the
chief judge of the circuit (or judge delegate). [18
U.S.C. § 3599(g)(2)][Guide, Vol. 7,
§ 660.20.20(a)]

The $ limit applies to the total payments of fees and expenses
for investigative, expert, and other services in a case (i.e., per
representation), not to each service provider individually. [Guide, Vol. 7,
§ 660.20.20(b)]
The $ limit does not apply to the cost of transcripts. [Guide, Vol. 7,
§ 320.30.10]
